This microbit Junior kit is a basic kit to kick-start your journey in digital making. Perfect for primary and secondary school students to learn coding, microcontrollers, LEDs, sensors, motors and more.

The micro:bit is a pocket-sized computer with a powerful ecosystem, a BBC initiative to get kids in the UK coding.

The micro:bit lets you get creative with digital technology. You can code, customise and control your micro:bit and use it for all sorts of unique creations, from robots to musical instruments and more.

At half the size of a credit card, you will be surprised at the amount of hardware each board is equipped with, including 25 red LED lights that can flash messages. There are two programmable buttons that can be used to control games or pause and skip songs on a playlist. The micro:bit can even detect motion and tell you which direction you’re heading. It can also use Bluetooth Low Energy (BLE) to interact with other devices.

Taking a closer look at the front of the board, we can see the 5x5 LED array that you can use as a light source, a tiny screen to draw on, display words, numbers and other information, and the two programmable buttons!

On the back of the board you will find the brains of the micro:bit, a 16MHz, 32-bit ARM Cortex-M0 microcontroller with 256KB Flash, 16KB RAM and a built-in temperature sensor. Additionally, the back of the micro:bit is populated by an accelerometer, compass and Bluetooth Smart antenna, as well as a micro-USB and battery connector for different power options.

Finally, at the bottom of the board, you will find 20 gold-tabbed edge pins and five ring connectors (three for digital/analog I/O, two for power and ground) for hooking up external components. The tabs with larger holes can be easily used with alligator clips to prototype with components quickly and easily - great for little hands!

The micro:bit even has an intuitive app which lets you send your code to your micro:bit over Bluetooth (without using a USB cable) and more.

With the micro:bit board and micro-USB cable included, you can start coding and having fun with micro:bit's LEDs, buttons and on-board sensors right away.

Combined with graphical programming from the online editor makecode.org, you can get started in less than 5 minutes! Perhaps start with the 5x5 LED matrix as a good visual output, displaying simple graphics or animation. Then try the two push-buttons (A and B) as digital inputs, and the built-in accelerometer for vibration and orientation detection.

There are tons of emoticons and example codes in the MakeCode Editor at your disposal. Students will enjoy learning art, music and coding, all at the same time.

This micro:bit Junior Kit comes with a special box too. The box can be used not just to store the micro:bit and USB cable, but also as a project box. The micro:bit can be mounted from inside of the box cover, exposing the LED matrix and push buttons, while protecting the other parts of PCB.

You can still program and power the micro:bit while it is attached underneath the cover as the box has been creatively designed to allow the access of USB cable from the rear.

The box is not only for keeping parts, but it is also part of projects :) There is plenty of space in there for many more components and extensions, so use it!
